Abstract

Abstract

The Cu-Au enrichment and mineralization is studied here. It is concluded that the different order structures in Altyn Tagh fault system controlled the spatial distribution of metallogenic belts,ore fields and ore deposits. Regionally,it is divided into north Altyn Tagh gold-copper-iron multi-metal metallogenic zone and Altyn Tagh iron-copper-gold multi-metal metallogenic zone. Two main mineralization periods occurring at 502.3Ma±10.1Ma and 207.6Ma±4.2Ma respectively have been recognized through the analysis of gold and copper abundances and ⁴⁰Ar/³⁹Ar geothermochronology. The evolution of tectonic stress field,related to the enrichment and mineralization of Cu and Au,is divided into three stages:pre-Mesozoic compression,Mesozoic extension and Cenozoic strike-slip stages. Areas with relatively low stress are prospected to be benefited for the enrichment and mineralization of Cu and Au.
